snuck onto the Wizard Chair at the base of Blackcomb, but at the top there were two guys waiting for me. They asked "why did you sneak onto the lift?"
I told them that I was up skiing and forgot my backpack at Rendezvous Lodge, with my "other" jacket in it with my pass. I had to sneak on because I needed to get up to the lodge to grab my pack with my ski pass in it.
They weren't really buying it, I told them that my wallet and everything is up in my pack, and all I really had on me that I could give them for collateral was my ski poles. Gave them my poles, got on the Solar Coaster Chair and just took off once I got to the top of the lift.
That's the closest I've gotten to actually getting caught skiing without a ticket. I haven't skied without a ticket/pass for like 8 years now though... man, I was ghetto in my early late teenage/early 20's.
